Abstract

The complex formation of p-aminoazobenzene and its derivatives with Fe(III) and Mn(II) has been studied by UV and IR spectroscopy and conductometry. The effects of solvents, donor basicity, and other factors on the formation of these complexes have been examined. The vatio of metal to ligand for the complexes formed is 1 : 1, both in the solid state and in solution. The stability constants of Fe(III)-donor and Mn(II)-donor complexes are in the range of 10$^2$∼10$^4$ and 0.1∼1, respectively. The absorptivities are ~10$^4$ and ∼10$^3$ l/mol${\cdot}$cm respectively. Thermodynamic properties such as ${\Delta}H^{\circ}$, ${\Delta}G^{\circ}$ and ${\Delta}S^{\circ}$ are calculated from their stability constants utilizing Van't Hoff equation.

Fe(Ⅲ) 및 Mn(Ⅱ)과 p-aminoazobenzene 및 그 유도체가 반응하여 형성된 착물들에 대하여 가시-자외선 및 적외선 분광광도법과 전기전도도방법을 이용하여 용매의 효과, donor의 염기도와 착물형성에 미치는 영향을 조사하였다. 그 결과 착물의 조성비, 안정도 상수 및 몰흡광계수를 구하여 van't Hoff식으로부터 ${\Delta}H^{\circ}$, ${\Delta}G^{\circ}$ 및 ${\Delta}S^{\circ}$를 계산하였으며 반응성과 등속도관계를 고려하여 반응속도와 평형조절인자를 알게 되었다.
